Any word on if new hardware support has been added with Nvidia’s 256.00.15a07 release? Are we starting to see early support for the 4xx series on the Mac Pro or are all of the driver updates just adding ATI product support with refinement and bug fixes for Nvidia & Intel IGP?

I’ve got a 6870 and tried the 10.6.5 beta but can’t get the card recognised. I suspect I am missing something though. I edited the ati5000controller.kext to add in the device id however just get a white screen when attempting to boot (gets passed the apple logo but hangs at a blank white screen before reaching the desktop).
